Report No: P21-01072015.
Report of potential failure of GE Hitachi (GEH) SBM type Switches per 10CFR Part 21 Pursuant to 10CFR 21.21 (b), AZZINLI has provided written notification to the affected licensees of the potential failure of GEH SBM type switches manufactured (by GEH) in the period from January 2012 to December 2014.This condition has been reported in GEH document SC 14-19 (dated Dec. 11, 2014) in which GEH notified their affected licensees of the potential failure of SBM type switches, manufactured and shipped January 2012 through December 2014, due to incorrect installation of a conical spring (see Figure 1). AZZINLI procured and dedicated commercial grade SBM type switches, manufactured during this time-frame, and subsequently provided to:* Exelon -Peach Bottom* OPPD -Fort Calhoun* TVA- Watts Bar" KHNP On the basis of our evaluation, it is determined that AZZINLI does not have sufficient information to determine if the subject condition would, or has, created a Substantial Safety Hazard or would have created a Technical Specification Safety Limit violation as it relates to the subject plant applications.
Therefore, purchasers are being advised to perform a visual inspection of the switches at the earliest opportunity to determine if the condition exists.The following information is provided per 10CFR 21.21 (d) (4).(i) Name and address of the individual or individuals informing the Commission.

GEH has attributed the root cause of this spring orientation condition to a change in sub-supplier for the contact carrier assembly.This change in sub-supplier occurred in 2011 and GEH received shipment of switches with the change in sub supplier no earlier than January 2012.(iii) Identification of the firm constructing or supplying the basic component which fails to comply or contains a defect.Commercial grade GEH SBM type switches procured from December 2012 through May 2014 and dedicated for Safety Related use by AZZ I NLI.(iv) Nature of defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.The cause of the failure was incorrect installation of a conical spring, which subsequently shifted and resulted in the switch failure. GEH determined that SBM switches shipped in the period from January 2012 to December 2014 may have the subject condition.
AZZINLI does not have sufficient information to determine if the subject condition would, or has, created a Substantial Safety Hazard or would have created a Technical Specification Safety Limit violation as it relates to the subject plant applications.
The GEH notification (document Sc 14-19) was not provided to AZZINLI, since AZZINLI does not procure SBM type switches from GEH as a basic component.(v) The date on which the information of such defect or failure to comply was obtained.On December 23, 2014, AZZINLI was initially notified of the GEH documentation regarding the potential failure of SMB type switches via email from an affected licensee in receipt of the GEH documentation.(vi) In the case of a basic component which contains a defect or falls to comply, the number and location of these components in use at, supplied for being supplied for, or may be supplied for, manufactured or being manufactured for one or more facilities or activities subject to the regulations in this part.
